We do the same thing but I cant remember what the cost was.. I want to say it was an extra $100.. or $60 a piece.. or something like that. They just charged it to our room number. I think you can put it on a separate credit card thought if you want (at the spa).

I think the aromatherapy 25 minute massage (there is no 30 minute) is $55. So I imagine you could just book both that massage and the free honeymoon massage at the same time and they'll just make it almost an hour long...

Everything is charged to your room, including spa services so you would pay upon check-out.
